On-metal NFC tags have a very thin ferrite layer between the chip and the adhesive part, in order to isolate the magnetic field of any metal surfaces. As a result, they can only be read on the non-adhesive side, and can also be applied to metal surfaces.

Tag Customization

We can print directly on this tag, in black and white or in full color. The printing time varies from 1 to 5 working days, depending on the quantities requested.

In both cases, a printing tolerance of about 1-2 mm should be considered. To achieve the best results, it is recommended to avoid:

• "Bleed" designs
• Graphic elements such as frames
• Important elements very close to the edge

Thermal Transfer Printing in Black

Thermal transfer printing is a printing technique that is performed directly on white labels. The print is in black, without shades. Thermal transfer printing is very durable and is designed to print an identifier, a QR code (even variable), or simple designs with a white background.

UV Color Printing

UV printing is a color printing technique that can be performed directly on white labels. The print is in CMYK and the result is semi-opaque. UV printed labels are supplied in strips (not on rolls). This method is ideal for small runs (typically under 500 pieces). For larger runs, we recommend Premium Express printing or offset printing. Contact us for more information.
